Spare Part: Jeep Wrangler JK 12-17 Supercharger Replacement Pulley Kit

The simple solution for more boost and horsepower from your Innovate or Sprintex S5-210 Supercharger system on the Scion FR-S, Subaru BRZ, and Toyota GT86. The 69mm pulley increases boost to 12 psi (stock is 9 psi) and puts the blower a little under the continuous operation redline. Expect an increase of 10-12 horsepower running on pump gas!
